The present invention relates to film holding boxes for cinematograph apparatus, more particularly to a ,very useful and practical shaping of the partition of such boxes.

In certain cinematograph apparatus film holding boxes are emplo ed which have a partition forming a cham r for the receiving spool and another for the delivery spool.

' This partition serves also as a ide for the pose. We found that this disadvantage is overcome by constructing box and partition in such a manner that the partition can easily be withdrawn, when the plush has been worn and a new one substituted for it. The blank for the partition is stamped from sheet metal and then' so bent that at one end of the partitiontwo U-shaped guides .are formed for the passage of the film, which at one end may be folde over in order to clamp the plush,

while at the other end ,the guide formingflan s form means for the light-tight connection with a side of the box, for example, they are bent over to lie parallel to'the partition so as to form two slots in which corre- 3 s nding inwardly rojecting stepped anges located on a wall of thebox can eng'age,-when the partition is inserted in the Iii theaocompanying drawings an embodiment of the invention is shown.

Fig. 1 is an elevation of a .stampedmetal blank from which the partition is formed. Fi 2'is'a side view of the partition made by to ding the-blank.

46 Fig. 3 is a view, drawn to an enlarged is securely clamped. The strip 8 'is held in position with suflicient security by conscale, showing the engagement of the partition with the box.

Fig. 4 is a section on line 4-4 of Fig. 3.

Fi 5 is a section through the*charged film ox.

Referring to Fig. 1, the stamped metal blank from which the partition is to be formed consists of a rectangular middle iece 1 bearing on the upper end of each ateral side a narrow strip 3 connected with 5 rectangular wings 4. To form the partition 2, the middle piece 1 is folded along the dotted line a in an angle of 180, whereat the end of the partition 2 formed is splayed for a part of its length to form a slot 16. Then the wings 4 are brought into position to form the U-shaped film guides 5 as'seen in Fig. 4, by bending the strips 3 twice inward at .right angles along the dotted'lines b indicated in-Fig. 1.

The ends 6 of the wings4 are bent twice rectangularl outward along the dotted lines d in or er to form holders for the plush material 8. The ends 7 of the wings 4 are folded along the dotted lines o outward and. bent in the form of stairs along the lines 6 to form uide slots 15 for receivlng the stepshaped anges 10 provided on the side wall 9 of the box as seen in Figs. 3 and 5. Notches 14 are rovided as well in the middle piece 1 as in t e wings 4 which after folding the partition in the manner described are adjacent to each other.

Into each film guide, thus formed by the win 4, are inserted plush material 8 and 8 die Fig. 5) between which the film 13 is to pass. The strips 8 aresecured by passing one end of the strip around the end 6 of the wing 4. By the bending at 6 the plush tact with the strip 8. The partition 2 is inserted in the box when the cover is removed by engaging the ends of the guideslots 15 of the partition 2 (formed as hereinbefore described by a suitable bending of the ends 7 of the wings 4) with flanges 10 on the side of the box and sliding it along these flanges until it rests on the bottom 12 of the box; the other end of the partition splayed for a part of its length at 16 slides on a pad 11 at the wall of the box.

For the exact positioning of the partition and furtherexclusion of light a ridge 17 is provided in the bottom 12 of the box, which ridge extends between the fiangeslO and enapparatus a removable partition separating forming a groove, and a pad on the side wall the film feeding and the film receiving compartments which partition has at one end two U-shaped guides for the film leaving and entering the box, and means for light tight connection with the sides of the box.

3. In a film holding'box for cinematograph apparatus a removable partition separating the film feeding and the film receiving compartments which partition has at one end two U-shaped guides for the film leaving and entering the box,'and two slot forming flanges in which slots engage two flanges inwardly projecting from a side of the box.

' 4. A removable partition in accordance with claim 3 formed by folding a stamped blank of sheet metal.

5. A removable partitioniin accordance with claim 8 formed by folding a stamped blank of sheet metal, the film guides being covered with plush material.

6. In a film holding box for cinematograph apparatus a removable partition in accordance with claim 3 formed by folding a being covered with plush material, the other end of the partition being splayed, thus of the box to engage with the said groove formed in the partition.

9. In a film holding box for einematograph apparatus a removable partition in accordance with c1aim 3 formed by folding a stamped blank of sheet metal, thefilm guides being covered with plush material, the partitures.
